Title: Microbiological features of aquifer thermal energy storage systems

Conference ·
OSTI ID:6368740

A study was initiated to determine the environmental effects of aquifer thermal energy storage (ATES) technology pertaining to microbial communities indigenous to ATES and the propagation, movement, and release of pathogenic microorganisms within ATES systems. Six water samples from various locations within a chill ATES system in Tuscaloosa, Alabama, were obtained to develop a microbial profile. In addition, two head wells were sampled using glass slides/solid support device (SSD) to assess the importance of adhering microbial populations. Bacteria were observed in all water samples collected Heterotrophic bacteria represented the largest group observed. In addition, coliforms and pseudomonad (bacteria that may be opportunistic human pathogens) were observed in many of the samples. However, no true human pathogens were observed in the water or solid support samples. Although preliminary, the data suggests that chill ATES does not increase the level of pathogenic microorganisms in aquifers. 14 refs., 1 fig., 5 tabs.
